Welcome to the Penrhyn Quarry Railway Society website. Formed in 2004, we are a support and historical group of the Penrhyn Quarry Railway.

Benefits of membership include our acclaimed quarterly journal, Y Llechen/the Slate, in which we specialise in previously unpublished historical research and photographs of the railway.

We have a range of exclusive merchandise featuring historical photographs from our extensive collection. These can be purchased from our on-line shop or from exhibitions that we attend with our publicity stand.

The railway is possibly the first two foot gauge railway in the world, the quarry is the largest slate quarry in the world, the slab mill is the oldest in Wales, and the inclines are the oldest in Wales. All this makes this iconic railway national, if not world, importance.
